Synscan EQ5 is also using a 12V power system. With its included cigarette jack power cable, it can go into many "12V Automobile JumpStart Battery" DC 12 Volt socket. Such devcie quite often can be found for $20 - $30 USD.

You should be able to find an AC-DC power adaptor that will allow you to run the mount from any normal household outlet. It looks very similar to a power adaptor that provides power to a laptop computer. I bought one for my CG5-ASTG when I'm observing from my patio. Works like a charm! I got it for around $22.00 shipped. Hope that helps.

If you want to buy an AC-DC power adapter, please make sure it is a 12V 2A (or more) Switching Power Supply. When such unit is used outdoors un-shelter environment, don't let it get wet or use it in very high humidity environment!

Be sure that the power supply you use is rated for about 1500 MA or better (1.5 amp). These mounts take very little power for tracking, but a long slew usually will draw over one amp.

You may find that you prefer to use a 12 Vdc power supply rather than the power tank when you are near an outlet because you simply don't have to worry about the power fading over the evening.

I made a very long cable for my power supply.. About 30 ft. I bought a thin 4 wire twisted pair cable from Fry's. Becasue the conducters were really small, I used one pair for + and one pair for -. Otherwise, I think the conductors would have been too small.

I like this cable because it doesn't "Twist up" like lamp cord and lays flat on the ground. It coils very easily too. I soldered on a male cigerette lighter plug on one end, and a three recepticle 12 Vdc plug on the other. This way I can run more than one scope, or I can run a scope and a dew shield, or a 12 vdc light.

Now I can just leave the 12VDC power supply plugged in all the time under the shelter of my covered porch and run the long power cord out. I have a power tank, but since doing this, I don't have to mess with it anyomre.

I have an EQ6 mount.I just use a 7 ampere hour lead gel battery soldered toa cigarette lighter socket.It can last for 5 hours or more as long as you don'tslew all the time.The socket cost me $8 from an electronics hobby store &the battery $35.I use a 14.2 Volt 5 Amp DC power supply to charge it up again.The advantage is - no long cables - it just sits under the mount. You wouldn't want anyone to trip over a cable inthe dark - especialy if it was you, carrying your expensivetelescope back inside at the end of the night.Dropping a telescope can easily ruin it.

If I wanted to I could buy a bigger battery.The next size up is 17 Ampere hours which would last allnight even if you were constantly slewing.
